Kalwall has been providing museum-quality daylighting™ to building occupants all over the world for more than 65 years. Our company dates back to the invention of the original translucent sandwich panel by inventor and company founder Robert R. Keller, Sr. in 1955. No other company in the world has dedicated more years, resources, creativity and innovation into the science and art of daylighting. Kalwall provides building designers and owners with the most advanced technologies in the world to fulfill their own visions of creating better buildings for people that balance performance, economy, and beauty.
Solatube International has revolutionized the way daylight is brought into a building. Known as a tubular daylighting device (TDD), our products are a compact and leak-proof alternative to traditional skylights, virtually eliminating glare and minimizing solar heat gain.
Unlike traditional skylights, our products capture the sun’s light and deliver it to indoor spaces where natural light was previously unheard of, like interior rooms, and rooms on lower floors. And only Solatube Daylighting Systems use breakthrough technology to transform virtually any room in only two hours—without the costs, leaks and hassles associated with traditional skylights.
Using advanced optics and breakthrough delivery technologies, our early designs earned accolades from industry experts and customers alike for their high performance and engineered simplicity. Since then, we’ve continued to lead the daylighting industry with optical improvements and decorative enhancements that enable our products to capture and transfer even more daylight into interiors.
Kalwall offers the most highly insulated light transmitting products in the market. Their high performance translucent building products range from standard Wall and Skylight Systems to Unitized Curtain Walls, Canopies+Walkways, Skyroofs®, and ClearspanTM Systems.
Kalwall is the most highly insulating, diffuse light-transmitting, structural sandwich panel in the world. While there are other translucent products on the market, none can match Kalwall’s ability to provide unparalleled light quality and superior thermal performance at a reasonable cost. In the sixty years that they have worked with lightweight, composites technologies, Kalwall has perfected this unique fenestration technology that harvests balanced, natural daylight while providing the ultimate in energy efficiency.
